They are both rather famous kitbashes done by Squal2932937 or something. He post regularly on the kitbashing section of this board.
If you're reading this Squal, sorry for forgetting the number in your user name.

A name is a name, make of them what you will. I actually prefer some of Hasbro's because especially in Energon they didn't force G1 names on everything, like Bulkhead. But that's by the by, everyone has their own preference of course.

Only if you insist that every character in the Armadaverse should have the same name as the G1 Character they most closely resemble. (even though all the Characters you mention have almost nothing in common personality wise with the G1 Bots that you imply are their equivalents)

And the Armada Versions were developed under the US names before Takara decided to rename them with more G1-like names rather than translate the existing names.

It's not even as if theres much resemblance between Armada Red Alert and Rachet: except for a colour ccheme and general Alt mode theme thats been common to every single TF Medic.

And anyway Cybertron Red Alert wasn't named "Rachet" in Japan either, he was "First Aid" and then "First Gunner"

Perhaps "First Aid" is a bit off as both Ratchet and Red Alert. But I think it is only logical that the obvious G1 name should be applied if the figure is already a tribute to a g1 character, or the name itself has similarities to the alt mode. Grapple / Smokescreen is a good example.
